Repair kit

From KayakWiki

The size of the repair kit depends on the nature of your trip. If you are just paddling around the local lake you may not need anything.

If you are crossing the Atlantic solo, you might want a bit more.

Your repair kit should contain most or all of the following in a waterproof container or drybag stowed in an easily-accessible location.

For emergency hull repair information and things to include in this kit, check Emergency kayak repair materials.
